(author)Technical specifications for the asphalt concrete properties are developed to be able to specify mixtures that will perform well in pavement applications. Being able to identify and determine properties related to pavement performance in practice is crucial for both road authorities and contractors, since it allows for design and risk management...book 2015

(author)In 2008 Europe introduced the CEN standards for Asphalt Concrete. The Netherlands adopted the approach of functional requirements, rather than empirical, recipe based requirement. The experiences since 2008 showed that, although this approach allows for a better, more fundamental understanding of Asphalt Concrete, the current understanding is...conference paper 2015

Erkens, S.M.J.G. (author), Van Dommelen, A.C. (author), Van Vliet, D. (author), Leegwater, G.A. (author)Het zelfherstellend vermogen, of de healingscapaciteit, van asfaltmengsels wordt in de meeste ontwerpmethoden voor wegverhardingen meegenomen. De kennis over dit zelfherstellend vermogen is gebaseerd op ervaringen en onderzoeken uit het verleden en de werkelijke mechanismen erachter zijn niet bekend. Hierdoor is het moeilijk om voor nieuwe...report 2014

On the combined effect of moisture diffusion and cyclic pore pressure generation in asphalt concreteVarveri, A. (author), Scarpas, A. (author), Collop, A. (author), Erkens, S.M.J.G. (author)In this paper, a new moisture conditioning protocol which attempts to distinguish the contributions of long- and short-term moisture damage, i.e. moisture diffusion and cyclic pore pressure generation, in asphalt mixtures is presented. The capability of the proposed protocol to rank various asphalt mixtures of known field performance for their...conference paper 2014

Erkens, S.M.J.G. (author), Scarpas, A. (author)With the increasing drain on natural resources and resulting aim to reduce the environmental impact of road engineering, the use of reclaimed asphalt in fresh asphalt becomes more and more important. Despite the experience in using RAC, there are still many questions regarding the effect of RAC on the technical and environmental performance of...book 2013

(author)Bituminous binders are known to have microstructures at typical length scales of micrometers. This microstructure can be probed with Atomic Force Microscopy (AFM). Now that worldwide several research groups are reporting AFM results on bitumen, it is becoming important to improve the understanding of the reproducibility and objectivity of the...conference paper 2013

Schmets, A.J.M. (author), Nahar, S.N. (author), Dillingh, B. (author), Fischer, H. (author), Scarpas, A. (author), Erkens, S. (author)In this report we present the background, the scientific and experimental approach and the results of AFM experiments performed on two different batches of bitumen. The specific bitumen researched in this project has also been studied in the context of the InfraQuest project ‘Pragmatisch Healing Onderzoek’. It has been known for quite some time...report 2012
